Cancel Sixt Car Subscription: The Right Way

How to cancel your Sixt car subscription and reclaim your money

Why you might want to cancel your Sixt subscription

Life changes. You might have secured a company car, relocated closer to public transport, or realised the monthly cost no longer suits your budget. Sixt car subscription gives you flexibility in theory, but cancellation involves formal notice periods and specific procedural steps that many subscribers overlook.

Understanding your cancellation rights under the Consumer Rights Act 2015 is your first line of defence against unexpected charges. Tocancel exists to guide you through this process with clarity and confidence, ensuring you know exactly what you're entitled to and how to act on it.

Common reasons subscribers cancel

People cancel Sixt subscriptions for genuine life changes: a new permanent job with a company vehicle, moving to an area where car ownership becomes unnecessary, financial hardship, or simply discovering that the monthly cost exceeds what they'd pay for traditional car ownership. Some subscribers realise too late that mileage limits and excess fees add up faster than expected.

The cost of missing your cancellation deadline

Missing Sixt's notice period can trap you in additional monthly charges of £450 to £1,500 depending on your vehicle tier. Even a single missed deadline locks you in for another full month. This is why Tocancel emphasises the importance of submitting your cancellation notice well in advance and keeping proof of your submission.

Your consumer rights and what they mean for you

You have clear legal protections when cancelling a car subscription contract in the United Kingdom.

What the consumer rights act 2015 protects

The Consumer Rights Act 2015 ensures that contract terms must be fair, transparent, and not deliberately loaded in the trader's favour. This means Sixt cannot impose unreasonable notice periods, cannot charge you indefinitely after you've cancelled, and must clearly communicate cancellation procedures in your contract terms.

Your legal position is straightforward: once you provide valid cancellation notice, you remain liable only for charges up to the end of that notice period. You are not liable for charges beyond it. If Sixt continues to charge you after your notice period expires, you have grounds to dispute those charges with your bank or credit card provider and escalate to the Financial Conduct Authority (FCA) if necessary.

The cancellation notice period requirement

Sixt requires formal written notice of cancellation, typically with 30 days' advance warning. This is a contractual requirement, not a preference. You must submit this notice in writing by email, post, or through the Sixt app to meet the legal standard. Verbal requests or informal messages do not constitute valid notice.

Your right to proof of cancellation

You have the right to request written confirmation from Sixt that your cancellation notice was received. Keep all email confirmations, app screenshots, and postal receipts. If Sixt later claims no cancellation was received, this proof protects you in disputes. Tocancel always recommends saving everything related to your cancellation.

Pricing and what's included in your subscription

Understanding your current costs helps you decide whether cancellation makes financial sense.

Sixt subscription tiers and monthly costs

Sixt offers five main vehicle categories, each with a fixed monthly price that includes insurance, road tax, servicing, and breakdown cover.

Additional charges that apply during your subscription

Beyond the monthly fee, you may face excess charges (typically £1,000 per incident), excess mileage fees (usually 20-30p per mile over your allowance), and repair charges for damage beyond fair wear and tear. These add up quickly and are often the trigger for cancellation decisions. When you cancel, ensure you've settled all outstanding charges to avoid disputes during the wind-down process.

How to cancel your Sixt car subscription

Sixt offers three formal methods to cancel your subscription, each with specific requirements and timelines.

Method 1: cancel online through the sixt+ app

This is the fastest and most straightforward route if you have the app installed and active on your account.

1. Open the Sixt+ app and log in with your registered email and password.
2. Navigate to "My subscriptions" or "Account settings" (the exact label varies by app version).
3. Select the active subscription you wish to cancel.
4. Choose "Request cancellation" or "End subscription."
5. Review the cancellation date and confirm your request.
   • The system will display your notice period end date (typically 30 days from submission).
   • Your subscription charges will stop after this date.
6. The app will send you an immediate on-screen confirmation and a follow-up email within 24 hours.
7. Save or screenshot both confirmations as proof of your cancellation request.

Method 2: cancel via email to Sixt customer services

Email cancellation is equally valid and often leaves a clear paper trail.

1. Compose a new email to Sixt's customer services (check your contract or the Sixt website for the exact address, typically something like [email protected]).
2. Include your full name, subscription reference number, current vehicle registration, and email address.
3. State clearly: "I request cancellation of my Sixt car subscription, effective [date 30 days from today]."
4. Include the date you're sending the email.
   • This serves as your formal notice submission date.
   • The 30-day notice period runs from this date, not from when Sixt reads the email.
5. Request a written reply confirming receipt and the cancellation end date.
6. Send the email from your registered email account (the one associated with your Sixt subscription).
7. Save the sent copy and any confirmation reply in a dedicated folder.

Method 3: cancel by formal post to sixt's registered office

This method is legally bulletproof but slower; use it only if app or email options fail.

1. Write a formal letter on plain paper or headed notepaper, including:
   • Your full name, address, and phone number.
   • Your subscription reference number and vehicle registration.
   • A clear statement: "I hereby cancel my Sixt car subscription, notice effective [date 30 days from today]."
   • The date you're sending the letter.
2. Address the letter to Sixt's registered office (you'll find the address in your contract or on the Sixt website; as of 2026, this is typically Sixt's UK head office in London).
3. Send the letter by Royal Mail Special Delivery, which provides proof of posting and delivery date.
4. Keep the Special Delivery receipt; this is your evidence that notice was submitted on a specific date.
5. Allow 3-5 working days for postal delivery and request a written acknowledgement if possible.

What happens after you submit your cancellation

Submitting your cancellation notice doesn't end your obligations immediately; you enter a wind-down period with specific milestones.

Your notice period and final payment date

From the date Sixt receives your cancellation notice, you have exactly 30 days remaining on your subscription. Sixt will continue to charge you the monthly fee for this full period. On day 31, your subscription expires and all charges cease. Mark this date on your calendar and verify on day 32 that no new charge has appeared on your card.

What you must do during the notice period

You remain responsible for the vehicle during these 30 days. You must continue to pay any charges incurred (excess mileage, damage repairs, parking fines, congestion charges) and maintain the car to the standard required in your contract. Arrange a return inspection with Sixt well before your final date to identify any issues and avoid surprise excess charges after cancellation.

Vehicle return and inspection

Contact Sixt to arrange a final inspection appointment. During this inspection, Sixt assesses the vehicle's condition against the terms of your agreement. Document the condition yourself with photos or video before the inspection; this protects you if Sixt later claims damage you dispute. A fair wear and tear assessment is required by law; Sixt cannot charge you for normal use and minor marks.

Refunds and final billing after cancellation

Understanding what refunds you're entitled to prevents disappointment when you receive your final statement.

When you receive money back

Sixt typically refunds any overpayment within 10-14 days of your subscription end date. This includes unused portions of your final month if you cancel mid-month (though the 30-day notice period usually means you pay in full for that final month). You should also receive refunds for road tax, depending on the tax band of your vehicle and how much time remains on the tax disc.

You will not receive a refund simply for cancelling early; you're paying for a service used up to your notice period end date. However, if you've paid for services beyond that date (for example, breakdown cover), you may request a pro-rata refund.

When you owe additional charges

If the vehicle inspection reveals damage beyond fair wear and tear, excess mileage overages, or outstanding fines or charges, Sixt will invoice you for these amounts. You have the right to dispute these charges in writing within 14 days if you believe they're unfair. Tocancel recommends obtaining a detailed breakdown of any charges and comparing them against your contract's damage and mileage terms.

How refunds are processed

Refunds are returned to your original payment method (credit card, debit card, or bank transfer). If you've changed your payment details since you started the subscription, contact Sixt to update this information before your cancellation end date. Allow 5-10 working days for the refund to appear in your account after Sixt processes it.

Common mistakes that delay your cancellation

Cancelling a Sixt subscription feels straightforward until something goes wrong. Here are the pitfalls that catch most people off guard.

Submitting cancellation notice too close to your renewal date

If you submit your 30-day notice just before Sixt's monthly billing date, you'll still be charged for the next full month. Plan ahead: if you want to avoid an extra charge, count back 30 days from your next billing date and submit your notice before that date. Tocancel's checklist (see below) includes a date calculator specifically for this reason.

Assuming verbal or informal cancellation counts

A casual chat with a Sixt employee, a phone call, or a message via social media does not constitute valid cancellation notice. Sixt requires written notice by email, app, or post. If you've spoken to someone verbally, follow up immediately with an email repeating your cancellation request and referencing the conversation. Keep records of both.

Missing the final inspection appointment

If you don't arrange a formal inspection, Sixt may assess the vehicle without your presence and charge you for alleged damage you didn't see or agree with. Always schedule an inspection, attend in person, and request a written damage report before you leave the car.

Forgetting to request confirmation of cancellation

Never assume cancellation is complete just because you submitted notice. Request written confirmation from Sixt showing the exact cancellation end date. Without this, you have no proof if Sixt later claims the notice was never received and continues billing.

Use this step-by-step checklist to stay on track and avoid delays.

Comparing Sixt car subscription with alternative transport options

Before you cancel, consider whether alternatives truly suit you better or whether your cancellation is premature.

Sixt subscription versus traditional car hire

Traditional car hire (daily or weekly rental) suits occasional trips; Sixt suits regular use. If you're cancelling because you rarely drive now, sporadic hire is cheaper. If you're cancelling because monthly costs feel high but you use the car regularly, traditional ownership or a different subscription model might surprise you with hidden costs.

Sixt subscription versus car finance and ownership

Owning a car via a finance agreement locks you into a longer commitment but often costs less per month once you factor in insurance, tax, and servicing. However, depreciation risk stays with you. Sixt transfers all that risk to the company. Use an online calculator to compare true cost of ownership against your current Sixt monthly payment before you decide.
